- New view predicate: match_val. The ``match_val`` value represents
the presence of a value in the structure added to the request named
``matchdict`` during URL dispatch representing the match values from
the route pattern (e.g. if the route pattern has ``:foo`` in it, and
the route matches, a key will exist in the matchdict named ``foo``).
Like all other view predicates, this feature is exposed via the
``bfg_view`` API, the Configurator ``add_view`` API, and the ZCML
``view`` directive.
Documentation
-------------
- API documentation for the ``add_view`` method of the configurator
changed to include ``match_val``.
- ZCML documentation for ``view`` ZCML directive changed to include
``match_val``.
- The ``Views`` narrative chapter now contains a description of the
``match_val`` predicate.
Bug Fixes
---------
- The ``header`` predicate (when used as either a view predicate or a
route predicate) had a problem when specified with a name/regex
pair. When the header did not exist in the headers dictionary, the
regex match could be fed ``None``, causing it to throw a
``TypeError: expected string or buffer`` exception. Now, the
predicate returns False as intended.
Internal
--------
- Remove ``repoze.bfg.configuration.isclass`` function in favor of
using ``inspect.isclass``.

This URL is a subclass of the built-in Python exception named
``UnicodeDecodeError``.
- When decoding a URL segment to Unicode fails, the exception raised
is now ``repoze.bfg.exceptions.URLDecodeError`` instead of
``UnicodeDecodeError``. This makes it possible to register an
exception view invoked specifically when ``repoze.bfg`` cannot
decode a URL.

``repoze.bfg.configuration.Configurator.add_static_view``. Before
1.3a4, view names that contained a slash were supported as route
prefixes. 1.3a4 broke this by trying to treat them as full URLs.

``_app_url`` is present in the arguments passed to ``route_url``,
this value will be used as the protocol/hostname/port/leading path
prefix of the generated URL. For example, using an ``_app_url`` of
``http://example.com:8080/foo`` would cause the URL
``http://example.com:8080/foo/fleeb/flub`` to be returned from this
function if the expansion of the route pattern associated with the
``route_name`` expanded to ``/fleeb/flub``.
- It is now possible to use a URL as the ``name`` argument fed to
``repoze.bfg.configuration.Configurator.add_static_view``. When the
name argument is a URL, the ``repoze.bfg.url.static_url`` API will
generate join this URL (as a prefix) to a path including the static
file name. This makes it more possible to put static media on a
separate webserver for production, while keeping static media
package-internal and served by the development webserver during
development.

dispatch route (each of the predicate functions fed to the
``custom_predicates`` argument of
``repoze.bfg.configuration.Configurator.add_route``) has always
required a 2-positional argument signature, e.g. ``(context,
request)``. Before this release, the ``context`` argument was
always ``None``.
As of this release, the first argument passed to a predicate is now
a dictionary conventionally named ``info`` consisting of ``match``,
``route``, and ``mapper``. ``match`` is a dictionary: it represents
the arguments matched in the URL by the route. ``route`` is an
object representing the route that matched. ``mapper`` is the url
dispatch route mapper object.
This is useful when predicates need access to the route match. For
example::
def any_of(segment_name, *args):
def predicate(info, request):
if info['match'][segment_name] in args:
return True
num_one_two_or_three = any_of('num, 'one', 'two', 'three')
add_route('/:num', custom_predicates=(num_one_two_or_three,))
